Donghae is slowly showing his true self towards the end of the episode. Look how he lends his coat to Eunseo and leads her to the car. Even if Hae is not a prof in dating, he is definitely not an amateur.

I'm so glad to see Donghae slowly revealing his more romantic side. I adore both his adorkable side and his romantic side. But like he said, he can't stay awkward forever ❤ And I hope we start getting to see Eunseo's more spontaneous and true nature, she's been even more quiet than Donghae xD

We've at least seen Donghae's kid-like side with Teukie and Sora, I'm curious to see Eunseo's true nature. She likes kickboxing so she must be a spontaneous and brave sporty-type girl, so I hope she starts showing that side of her.
